摘要：

Geometrical structures of various isomers in the HC4N molecule were studied by the second-order Moller-Plesset perturbation (MP2) method with the Huzinaga-Dunning D95** basis set. The relative stability was obtained using the single-reference SDCI + Q method with the general contraction scheme of the [5s3p2d1f(C and N)/3s2p1d(H)] basis set. The most stable isomer is a singlet (1) with a C3-ring, being 8.6 kcal/mol lower in energy than the triplet linear 6. Several isomers exist within 1 eV of the most stable species.
